Question about 1999 Ford F150 Regular Cab

1999 f150 anti lock brakes

My 99 f-150 has the abs warning light on in the dash as well as the brake light as if the e brake was on. It also failed inspection because the passenger side rear wheel is not working properly. I did bleed the rear brakes after inspecting the shoes and it looks ok. I was trying to find an abs module out of a scrap vehicle but don't know where it is located in the truck or what it looks like. I could be looking for something I don't really need.
Can anyone help me solve this issue! jpm7481@yahoo.com
Thanks, John

    My truck does not have sensors in the front wheels at least I could not find any. I did pull the speed sensor out of the rear and cleaned it. I did adjust the right rear brake, spun the tire and it seems to stop the wheel under no pressure. Some of these trucks only have rear wheel anti lock systems. Mine has a block with 3 lines to it directly under the master. I wonder if it can be pulled off and cleaned out with out any major headaches?

    the fluid needs to be changed, it is darker than is should be. I will change that when I clean the module to see if that helps.

    Other than Ford,where can I get another module that is not going to cost me an arm and leg?

John, My 99 F150 had an abs light on and I found the right side front wheel sensor wire had fallen off of the inner fender mount and burned the insulation and grounded the wires together, I taped up the wires and tied it up and the light went out. Your ABS module is located directly beneath your air cleaner next to and just above the steering gear box. It is black plastic and silver alumnium. Says Kelsey-Hayes right on and has six brake lines attached to it. As for the rear brake take that drum off again and have someone help by pushing the brake pedal down while the drum is off press lightly and very slowly, verify that the brake cylinder is moving, do not push hard and fast as it will probably blow the pistons out of the cylinder! If is is frozen replace it and bleed and it should be fine. The brake light is probably on for low fluid. Let me know how it goes.

    It should have front ABS, look at the master cylinder lines, do both of them go to the ABS module or one one? If only one then it may only have rear wheel ABS, The module can be pulled and cleaned however if it has a problem causing the light it is usually an electronic problem requiring replacement, what color is your brake fluid? still clear?

My abs light on my 2000 buick lesabre will not shut off i have replaced rotors and pads what could the problem be


The warning light indicates that there is a malfuction in the anti-lock Brake System (ABS). Normally the system will then cease to function so you have a conventional braking system with no anti-lock feature to engage if you lock up the wheels on braking.

This ABS fault warning has nothing to do with the condition of the pads and rotors so renewing them, which is essential for good braking performance, will not solve the problem.

You will need to take the vehicle to a mechanic with the correct equipment to diagnose the cause of the ABS warning. It may be as simple as a failed ABS sensor (or sensors) and that is what I would be checking first.

It is quite safe to drive the vehicle with the ABS disengaged because your brakes will operate normally. What you don't have is the ABS kicking in to release the brake pressure temporarily in the event you brake hard and lock up any of the wheels.

I have a warning light on my dash saying there is a problem with the ABS system. Is this a safety problem?


not really. Measn that you most likely have a wheel speed sensor bad. Most often its in the front of the truck and its replaced with the wheel bearing. Although the system is disabled while the light is on the vehicle brakes are not affected

Problem with my cruise control and ABS light on 03 Explorer


Anti-Lock Control —Vehicles Built After 03/2002 The 3-channel anti-lock brake system consists of the following components:
  • front wheel speed sensors
  • front wheel speed sensor rings
  • hydraulic control unit (HCU)
  • Anti-lock brake control module (ECU)
  • rear wheel speed sensor
  • rear wheel speed sensor rings
  • yellow anti-lock brake warning indicator
The 4-channel anti-lock brake system with traction control and stability assist system consists of the following components:
  • active brake booster with integral solenoid
  • brake booster release switch
  • front wheel speed sensors
  • front wheel speed sensor rings
  • hydraulic control unit (HCU)
  • stability assist module (ECU)
  • stability assist event indicator
  • lateral accelerometer
  • longitudinal accelerometer (4x4)
  • rear wheel speed sensors
  • rear wheel speed sensor rings
  • steering wheel position sensor
  • yaw rate sensor
  • yellow anti-lock brake warning indicator
  • brake pressure transducer
  • traction control switch
---------------------------------------------------------------------
I suspect the abs issue is causing the speed control not to work if it happened at the same time the cruise control stopped working. When the yellow ABS light comes on, it means the ABS is dactivated. You may have a faulty accelerometer which senses acceleration and yaw (side to side lean). I have not seen a bad one but you said it is sensitive to acceleration.
I would unplug it and see what happens. The connector should have a small tab to depress so you can pull the connector out.
Here is where it is:

Accelerometer Removal and Installation
  1. NOTE: The accelerometer is located under the center, rear passenger seat carpet. (I think you have to remove seat for access).
    Cut the carpeting along the perforations.
  1. Disconnect the electrical connector.
  1. Remove the nuts and remove the accelerometer.

Have dealer hook up tester and pull fault codes if you can't find an easy solution.
Some background info
  • A malfunction in the anti-lock brake system will cause the anti-lock brake control module to shut off or inhibit the system. However, normal power-assisted braking remains.
  • Malfunctions are indicated by the yellow ABS warning indicator in the instrument cluster.
  • The anti-lock brake system is self-monitoring. When the ignition switch is turned to the RUN position, the anti-lock brake control module will carry out a preliminary self-check on the anti-lock electrical system indicated by a three-second illumination of the yellow ABS warning indicator in the instrument cluster.
  • During vehicle operation, including normal and anti-lock braking, the anti-lock brake control module monitors all electrical anti-lock functions and some hydraulic operations.
  • Each time the vehicle is driven, as soon as vehicle speed reaches approximately 20 km/h (12mph), the anti-lock brake control module turns on the pump motor for approximately one-half second. At this time, a mechanical noise may be heard. This is a normal function of the self-check by the anti-lock brake control module.
  • Pedal pulsation coupled with noise while braking on loose gravel, bumps, wet or snowy roads is normal and indicates correct functioning of the anti-lock brake system.
  • Warning Lamp Indicator
    The anti-lock brake system (ABS) uses the yellow ABS warning indicator to alert the driver of a malfunctions in the ABS.
    The yellow ABS warning indicator will come on to warn the driver that the ABS has been turned off due to a symptom that exists in the ABS. Normal power assist braking remains but wheels can lock during a panic stop while the yellow ABS warning indicator is illuminated.

    -----------------------------------------
    Please report back, I am curious if that is what it is. Good luck

    Dash warning light


    Do you mean the ABS and BRAKE lights? If so, the ABS module is bad which causes both lights to come on. After rebooting, the module gets tested and the ABS light will come on after a few seconds. If it a module problem the BRAKE light will also come on. The brakes will work normally, but will not provide the anti-lock feature.

    depending on the system if it is 2 channel or 4 channel one of the sensors that are located on the backing plate located behind calipers is eithier faulty or dirty you can try brake cleaner these sensors use a small magnet pickup device to sense when the wheel "locks up"
